Anatomy ee dareemaha trigeminal oo laamaheediina

Xididdada waa ku saleysan habka dareemayaasha jirka. Inta badan waxay yihiin cranial, in waxa ka soo baxay ee maskaxda. mid kale waa dareemaha trigeminal. Waa maxay anatomy ee dareemaha trigeminal?

Waa maxay?

dareemayaasha Trigeminal in qaab-dhismeedka waa dareemaha nooca isku qasan. 5 loola jeedaa in labada nin ee dareemayaasha cranial.

Waxaa ka mid ah oo xasaasi ah (centripetal afferent) iyo motor (culus) fiiloyin, dheehan on falalkooda dareemayaasha waxaa lagu kala qaado labada lagana rujiyey (xanuun iyo heerkulka) oo qoto dheer (proprioceptive) receptors. Bu'da innervation motor propulsion qaadeen oo innervates muruqa masticatory inta badan. Waxa ay dhab ahaan yihiin anatomy ee dareemaha trigeminal iyo deegaamaynta ah laamihiisa?

Dareemayaasha maskaxda ka baxo aagga of buundada. Imaatinka out of maskaxda, inta badan waxaa ka mid ah qaadataa meel on Ahraamta ee lafta temporal. On top waxaa ku kala qaybsameen saddex laamood dareemaha: orbital (r.ophthalmicus), maxillary (r.maxillaris) iyo mandibular (r.mandibularis).

dareemayaasha Tani waa oo xiiso in Takhaatiirta dareemeyaasha tan innervates meesha oo dhan wajiga. Waxay jeelyihiin in inta badan lagu arkay isaga oo soo gaartay inta lagu guda jiro supercooling, meesha dhaawacyada wajiga, cudurada qaar ka mid ah nidaamka muruqyada.

Waa maxay anatomy ee dareemaha trigeminal oo laamaheediina?

dareemayaasha orbital

laanta koowaad ee dareemaha trigeminal waa xididka ama ophthalmicus nervus orbital.

Waa laamaha thinnest ka dareemaha trigeminal kordhin. Waxa uu inta badan u qabata shaqo ee soo dhaweynta. Innervate maqaarka ee foodda, qaybo ka mid ah gobolka temporal iyo parietal, daboolka sare, xagga dambe ee sanka, hogaga, qaar ka mid ah lafaha wajiga iyo xabka qayb ahaan sanka.

Dhismaha dareemaha ka kooban yahay soddon xidhmo yar macdantaa dareemayaasha. Dareemayaasha galo godka isha ugu derbiga sare ee sanka ka orbital, taas oo soo diro laan si ay u block iyo abducens. In ka laama dareemayaasha orbital sare waxaa loo kala qaybiyey saddex yar oo khafiif ah dogob - lacrimal, kaliga iyo dareemayaasha ciliary.

deegaamaynta Close ee bu'da inta badan keenta in ay soo gaartay iyadoo ay sabab u dhaawac ama godka isha gobolka supraorbital.

dareemayaasha Ciliary, markeeda, foomamka ganglion ciliary ah, ku yaal soohdinta reer saddexaad hoose iyo dhexe ee dareemaha iftiinka. Waxay ka kooban oo ka mid ah dhammaato dareemayaasha parasympathetic ku lug innervation ee qanjidhada isha, iyo meesha periorbital.

dareemayaasha maxillary

laanta kalena waxaa ka mid ah dareemaha trigeminal waa maxillary ama nervus ku maxillaris.

Waxa uu ka baxo saabka cranial dhex kabsanayo. ka, wuxuu ku dhacaa fossa pterygopalatine-palatine ah. Gudbinta dhexdeeda galay dareemaha infraorbital kordhiyay daloolkan orbital hoose. Ka dib markii marayay therethrough, dareemayaasha waddaa in channel isla at derbigii ugu hooseysa kastana falagiisuu dhex ah. Wajiga waxaa ka mid ah iyada oo loo marayo soo baxa godka hoose orbital meesha jajabiyaa galay laamaha yar yar. Waxay sameeyaan xarunta la laamaha ee dareemaha wajiga iyo innervate maqaarka ee indhaha hoose, oo bushintiisa sarena ha iyo dusha sare ee dhinaca wajiga. Intaas waxaa sii dheer, by dareemayaasha laan tago maxillary sida dareemaha zygomatic laan sare alveolar la xirrira interlacement wareegsan ilkaha iyo laamaha ganglionic xira dareemaha maxillary la pterygopalatine ganglion-palatine.

guuldaradii ee dareemaha lagu arkay dhaawacyada weyn ka fool, neuritis, hawlaha on the ilkaha iyo JQSHM.

dareemayaasha mandibular

laanta saddexaad iyo kan ugu adag ee dareemaha trigeminal waa mandibular ama nervus ku mandibularis. In ay ka kooban waxa uu leeyahay, marka laga reebo laamaha xasaasi ah, ku dhowaad dhammaan of xidid motor of dareemaha trigeminal in kordhiyay ka xuduntii motor ah, motorius xuduntii, in muruqyada daanka hoose. Sidaas darteed nidaamka this siisa muruqyada xogta iyo maqaarka in daboolo. Dareemayaasha baxo dhaladii iyada oo kabsanayo (window gadood ama furitaanka) ka dibna u kala qaybiyey laba kooxood laamood:

• laamaha muruqa tag muruqa masseter ah - muruqa pterygoid, ku meel gaadh ah, sidoo kale innervated digastricus musculus.
• Laamood waa xasaasi u ah xabka loogu talagalay, iyo sidoo kale inay hoose ee saabka afka. Qayb ka mid ah laamaha innervate xogta iyo luqadda. The laanta neerfaha mandibular ugu weyn oo ugu dheer - alveolny hoose (in ilo kale - alveolar) dareemayaasha ku dhex socda kabsanayo dhimirka la halbowlaha homonymous iyo galaa daanka channel hoose waxaa la aasaasay halkaas oo plexus alveolar hoose.

Waxaan u qaadan karnaa in ay tahay laan ka mid ah dareemaha trigeminal sii. Jaantuska habdhiska dareemayaasha ee (qaab-dhismeedka) iyo hantida (fiber dareemayaasha isku dhafan) soo jeedin laan terminal this. In kasta oo xaqiiqda ah in ay qaab plexus dareemayaasha alveolar u liita, meeshii ay dhamaystirka yaabaa in loo tixgeliyo galo in kanaalka mandibular.

Koorsada macdantaa dareemaha

Waa maxay anatomy ee dareemaha trigeminal (qaabka iyo horumarka laamihiisa)?

Dhismaha ay la mid tahay in dareemaha trigeminal in mid ka mid ah laf-dhabarka dareemayaasha. dareemaha trigeminal waa unit weyn oo gaar ah - ganglion ku trigeminal. formation Tani waxa uu ku yaalaa fossa dhexe cranial. On dhinacyada oo dhan, waxaa ku hareereysan go'yaal of Mater Duuraa. Guntin ayaa dendrites in ay u sameeyaan saddex laamood weyn ee maamulaha ee dareemaha trigeminal. xidid dareemayaasha xasaasi guskiisa iyada oo lugta dhexe ee cerebellum ah, halkaas oo ay xiran yihiin saddex nuclei ee maskaxda - sare iyo kuwa dhexe, kuwaasoo mid walba uu ka kooban yahay neurons dareen gaar ah. Qaybta motor of dareemaha bilaabo ka motor xuduntii - motorius xuduntii.

Thanks to this heshiis, dareemaha la gaadhi kartaa marka ay labada maskaxda iyo unugyada ku wareegsan, oo sidaas waa ay xiiseyneyso Takhaatiirta dareemeyaasha.

Waa maxay noocyada ugu muhiimsan ee lesions caan ku dareemayaasha?

Cudurada of dareemaha trigeminal

Waa maxay geeddi ayaa saameyn ku leh awooda shaqo ee waxbarashada iyo sida ay saamayn ku yeelan karaan by dareemaha trigeminal?

Anatomy ee ay stroke predisposes in channelopathies horumarinta - laamaha dareemayaasha xadgudub marayay channel ama marinka qaababka wareegsan. Xaaladdan oo kale, aqoonta muuqaalka guud ee dhulka ee dareemaha, iyo qaar ka mid ah calaamadaha la mariyo kuu ogolaanayaa inaad dhigay heerka guuldaradii iyo qaadaan tallaabo ku haboon.

Arrin kale oo si siman muhiim u tahay saameynta ay unugyada ku wareegsan. Inta badan on neerfaha saamayn burada maskaxda. Ballaarinta, waxay gacan ka riixo ee uu u saftay iyo sawirka gaar caafimaad.

Anatomy ee dareemaha trigeminal (aqoonta laamood oo waxaa meelo ay wajiga qiyaas ah) si loo ogaado dhibic ka tago laamaha dareemaha ah, iyo habab ee elektarooniga ah garoomada si ay u kicin, ama, la siiyaa meesha uu laanta, fuliyaan daaweynta ku haboon cudurka sababaya, taas oo keentay in muuqaalka kore ee calaamadaha.

Daraasad ee dareemaha trigeminal

Study of shaqo ee dareemaha trigeminal la fuliyaa ee go'aaminta dareenka ee maqaarka, taas oo innervates, iyo sidoo kale in awoodda bukaanka in waqti iyo nasasho muruqyada calaaliyo. Research fuliyay by dhibcood dareemayaasha taataabasho ay ka bixitaanka wajiga. Sidee baad u ogaado sida ay xasaasi ah dareemaha trigeminal? Anatomy uu ogolaanayaa in ay go'aan ka hawl ah ee neurons dareenka, oo ku yaalla maqaarka hoostiisa.

Determination of dareen ah waa la fuliyay lagu rusheeyey xal qabow iyo kulayl ama suufka. dareen xanuun hubiyaa by taabashada cirbadaha.

Si aad u hubiso shaqo motor of bukaanka ah laga codsaday in ay qabtaan dhowr dhaq-cunidda.

In joogitaanka isbeddel bahal ah ayaa lagu arkay dareen ah in hal ama in ka badan meelaha ay innervation ama awood la'aanta bukaanka si ay u qabtaan dhaq si fiican u qaadka. Waxaa dhinaca daanka weecasho ee bukaan-socodka ama adkaashada murqaha xad-dhaaf ah. xiisad ayaa ku jiraa muruqyada masticatory waxaa lagu go'aamiyaa marka u riixriixan oo iyaga ka gees ah in falka lagu calaaliyo.

Waxa aad u baahan tahay inaad ogaato muuqaalka guud ee dhulka ee

anatomy qaab dhismeedka of dareemaha trigeminal waa lagama maarmaan u ah go'aaminta sax ah oo meesha dhaawaca. Garanaynin meeshuu yahay oo laan, oo calaamado clinical sifo ay guuldarro iyo waxa ay noqon kartaa mid adag, waxaa suurtagal ah si loo ogaado qorshaha mugga iyo daaweynta.

Aqoonta meesha iyo dabcan ka mid ah laamihii dareemaha ku dul garbaha of Takhaatiirta dareemeyaasha iyo neurosurgeons. Waa khubaro kuwaas oo inta badan soo food leh cudurrada ku dhuftay dareemaha trigeminal. Anatomy (photo helay MRI) si loo ogaado tabaha daaweyn iyo qaadaan tallaabo ku haboon.

Marka calaamadaha ugu horeeya ee lesions kala duwan laanta neerfaha waa in si degdeg ah gargaar u doonaysaan inaad dhakhtar si ay u sameeyaan baaritaan iyo daawada geynta sawir.
